HH-INNOWAX毛细管柱 天然气中微量乙二醇的取样测定

天然气采出后通过人工注入乙二醇作为水合物抑制剂，以预防设备和管道的堵塞。建立可行有效的天然气中微量乙二醇取样测定方法，有利于对乙二醇加注量的指导。

浩瀚色谱（山东）应用技术开发有限公司采用溶剂解吸型硅胶在管输压力下富集天然气中微量的乙二醇，再通过液体解吸后进行气相色谱分析。在现场取样体积10 m3、用10 mL解吸液处理的条件下，乙二醇的检测限可达到0．05 mg／m3。

Sampling and determination of trace glycol in natural gas
Sampling and determination of trace glycol in natural gas

After natural gas is extracted, ethylene glycol is injected artificially as a hydrate inhibitor to prevent blockage of equipment and pipelines. The establishment of a feasible and effective sampling and determination method of trace glycol in natural gas is beneficial to the guidance of the amount of glycol injection.



Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses solvent-desorption silica gel to enrich trace amounts of ethylene glycol in natural gas under pipeline pressure, and then conducts gas chromatographic analysis after liquid desorption. Under the condition of a sampling volume of 10 m3 on site and treatment with 10 mL of desorption solution, the detection limit of ethylene glycol can reach 0.05 mg/m3.
